Ansys Fluent

Vorteile

used v19R2, did the basic CFD, however, meshing on a simple geometry such as rounded pipe, seemed like a hassle. So you tell me if there is even worth going forward.

Nachteile

Where do I start.
1) The customer support, is now directed to the ansys forum, which I am sure, some indians are doing a good job on it, however, its a very badly maintained source. The previous version of going to portal and looking for a pdf (assuming due to some blessing, it is available), was a better approach.

If you cannot open a file, becuase someone is trying to send a snapshot, then please find it in your heart to buy a better anti-virus software. I am sure such a big company such as ansys can open an attachment, if it cant get everyone through the ticketing system, which by the way, is also not very useful, or so late, that the user, ends interest, or endures to find a new method, which does not require the crappy customer support of Fluent.
I am guessing that is a win win for Ansys fluent anyways.

3) The ticketing system, never was useful, as I said, needed to couple fluent with python, for v19R2, and appraently, that feature is not made yet. These are the times I wished, my supervisors had agreed on Star-CCM+, instead of fluent.

4) If something has been discontinued, or will be discontinued, take it out from the list of radio buttons or drop down menus. It is simple software engineering basic.

5) Also, again, I wished, the customer portal, were open to more appropriate documentation when required. Putting up everything online in form of instructions manual was a bad decision. Also, i am pretty sure, you had not notice, that the website, opens slowly,

Vorteile

Highly specialized algorithms for diverse geometry and calculation strategies, allowing multi-physics problems could be solved easily without over consuming your hardware resources. Helping us to save an enormous amount of time and effort in understanding and predicting complex phenomena, Ansys seems like a must-have for engineers of our era.

Nachteile

Being a part of the Ansys ecosystem, unlike simple academic softwares, you should at least be familiar with the system in order to fully operate their functions. But for an engineer / numerical simulation professional this should be done in no time.

Vorteile

As someone who used Ansys Fluent during my PhD studies for air quality, I found it to be a powerful but complicated simulation software. One of the best things about Fluent is that it allows you to create your 3D geometry using other software and save it in a format that Fluent can read, saving you the trouble of learning how to model in different software. The results provided by Fluent are excellent and provide a wealth of data for analysis, including animations and various plots.

Nachteile

While it has a user-friendly interface, it takes a lot of time to learn and is not very intuitive. I highly recommend trying some tutorials before diving in. Also, running complex simulations with a mesh of millions of elements requires a powerful cluster and can take a long time. The results are great, however, it's not always easy to get there. Errors often appear during the learning process, but the software has a strong community of users, open forums, and assistance to rely on.

Vorteile

Working in heat transfer domain, the software offers plethora of options for different types of thermal management techniques. The interactive user interface allows user to navigate through the options at ease and tutorial support offered gives additional boost to new entrants in the software

Nachteile

Some times the intrinsic details that needs to be tweaked based on experimental conditions remain stubborn and unrealistic causing the software to deviate from the outputs intended from a set of conditions

Vorteile

Fluent has numerous options to solve various types of flow. It produces fast and accurate results. According to comparison with experimental results, CFD results satisfy the researcher most of the time.

Nachteile

The software does not allow the user to modify the source code. It has some features to modify some interface but is not desirable for every researcher.

Vorteile

The ability to use it in batch mode and the possibility to implement udf

Nachteile

that you stoppt Gambit (it is much faster and often creates better grids)
the graphical support under linux
it is not possible to export the cases in older versions
